Mouse model | Description | The effect on LPL | Phenotype | Reference(s) |
---|---|---|---|---|
cld/cld | Autosomal recessive mutation in mouse chromosome 17, a naturally occurring mutation | The loss of LPL (and hepatic lipase) activity | Develop severe hyperlipidemia, milky serum, ischemia, cyanosis soon after birth, and died within 36–48 hours after birth. | [15] |
Lmf1 −/− | Global LMF1 deficiency by gene trap mutagenesis | The loss of LPL (and hepatic lipase) activity | Recapitulating the phenotypes of cld/cld mice. | [17] |
Sel1LAdipoq-cre | Adipocyte-specific SEL1L deficiency using adiponectin promoter-driven Cre | ER retention of LPL aggregates, and reduced LPL secretion | Postprandial hyperlipidemia and resistant to HFD-induced obesity with ectopic lipid accumulation in the liver upon HFD. | [22] |
Angptl4-Tg | Whole body overexpression of mouse ANGPTL4 | Significantly reduced postheparin LPL activity | Severe hypertriglyceridemia and chylomicronemia in fasted state; retention of chylomicrons in plasma after 24-hour fasting; reduced fat mass; increased lipolysis in adipose tissue; mild insulin resistance | [83, 84] |
Hepatocyte Angptl4-Tg | Hepatocytespecific overexpression of human ANGPTL4 driven by the ApoE promoter | Mildly reduced post-heparin LPL activity | Increased plasma triglycerides and cholesterol under fed condition. | [85] |
Angptl3 and Angptl8 | Overexpression of mouse ANGPTL3 by adenoviral infection or human ANGPTL8 by hydrodynamic DNA delivery | Not tested | Increased plasma triglyceride levels | [93], [92] |
Gpihbp1 −/− | Global deficiency in GPIHBP1 | Mis-localization of LPL in the interstitial space | Early onset of severe chylomicronemia within 4–14 weeks of age | [34, 38] |
Apoa5−/−; Apoa5 knockdown | Global knockout of Apo-AV; 60% knockdown of hepatic Apo-AV protein using targeted antisense oligonucleotide treatment | Decreased plasma LPL activity | Significantly increased plasma triglyceride levels; reduced plasma lipid clearance rate | [49, 50] |
Apoc1 overexpression | Hemizygous expression of the human apoc1 gene; | Not tested | Markedly increased plasma triglyceride levels; mildly increased plasma cholesterol levels | [55] |
Apoc3 overexpression | Overexpression of human apo-CIII | Not tested | Markedly increased plasma triglyceride levels; reduced clearance of VLDL triglycerides | [54] |
